Kiper didn't only write the line in ATTSS, she gave the initial idea taken from Fucking Amal. Ivan never said it was his idea and never objected Kiper's statements.

Yeah, he didn't say it was his idea, but I think he is very ungrateful to Kiper, making it sound like the only thing she did that was successful for the project was to write the line "Ya Soshla S Uma" - she did WAY more than THAT!

Kiper and Polienko were very special and determinant elements in this project.
